Highly chemoselective reduction of methyl 2- and 3-nitro-oxypropionate (9) and (12) with calcium borohydride was accomplished to give the desired 2- and 3-nitrooxypropanols (6 and 13) in good yields without affecting the nitrooxy group.
NO donors. Part 16: Investigations on structure–activity relationships of organic mononitrates reveal 2-nitrooxyethylammoniumnitrate as a high potent vasodilator
The vasoactive properties of 14 organic mononitrates were investigated in vitro using PGF(2 alpha)-precontracted porcine pulmonary arteries. A surprisingly wide range of vasorelaxant potencies was observed (pD(2): 3.36-7.50). Activities showed to be highly sensitive to the molecular structure and the substituents at the molecular carrier of the nitrate group. A correlation between lipophilicity and vasorelaxant potency could not be recognized. 2-Nitrooxyethylarmmoniumnitrate (1) was found to be slightly superior to the high potency trinitrate GTN.

The present invention relates to a method for reducing the production of methane emanating from the digestive activities of a ruminant and or for improving ruminant animal performance by using, as active compound at least one nitrooxy alkanoic acid and/or derivative thereof, which is administrated to the animal together with the feed. The invention also relates to the use of these compounds in feed and feed additives such as premix, concentrates and total mixed ration (TMR) or in the form of a bolus.
